Everything You Need to Know About Wet Media Milling, …

The first step to wet grinding is eliminating air from the surface of the raw feed, so that each individual particle is fully in contact with the liquid slurry. Ensuring complete contact is vital for effective milling. This requires a liquid with lower surface tension than the free surface energy of the solid.

Determining the Right Mill or Grinder for Your Application

Impact: Force at a solid surface is achieved by opposing particle acceleration. Examples: mixer mills, planetary mills, impact mills, jet impact mills, drum mills. Friction: Force results from vertical pressure of one surface and simultaneous movement of another surface. Examples: mortar grinders, disc mills, hand mortars, rod …
